Have you ever plucked an eyeball out of a fish and eaten it? Any health risk?

[Jack Rhodes]

I've always been amazed at the differences in my wives chinese culinary culture and mine, american. She had prepared a fish and ate most of the head. I jokingly commented that I am surprised that she didn't eat the eyes too. When I said this, she took her chop sticks and pluck out one of the fish eyes and ate it! Then she turned the head over and ate the other one too! Have you? Any health risk?
